0 Pulmosil Inj 12.5ml (Sildenafil) works by inhibiting the enzyme PDE5, which is responsible for breaking down cyclic guanosine monophosphate (cGMP).1 cGMP is a molecule that relaxes smooth muscle cells in the blood vessels, allowing for increased blood flow.2 By inhibiting PDE5, sildenafil allows cGMP to remain active for longer, leading to relaxation of the smooth muscle cells in the blood vessels of the penis, enhancing blood flow and facilitating an erection.3 In the case of PAH, sildenafil works by relaxing the blood vessels in the lungs, reducing blood pressure and improving blood flow.
